Impatiens plant named ‘Balpixropi’

ABSTRACT

A new and distinct  Impatiens  plant named ‘Balpixropi’, characterized by its small rose-pink flowers, compact growth habit and dark green leaves.

Latin name of the genus and species of plant claimed: Impatiens walleriana.

Variety denomination: ‘Balpixropi’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Impatiens plant, botanically known as Impatiens walleriana and hereinafter referred to by the cultivar name ‘Balpixropi’.

‘Balpixropi’ is a product of a planned breeding program with the objective of developing Impatiens cultivars with small flowers and compact growth habits.

The female or seed parent of ‘Balpixropi’ was an unnamed Impatiens plant. The male or pollen parent of ‘Balpixropi’ was a mix of pollen from plants of the Impatiens series SUPER ELFIN. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross during October 1999 in a controlled environment at Elburn, Ill. The new cultivar was initially designated ‘BFP-515’.

Asexual reproduction of the new cultivar has been carried out at West Chicago, Ill. by terminal tip cuttings and has demonstrated that the unique characteristics of the new cultivar as herein disclosed are firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) exhibits small rose-pink flowers;

(b) forms dark green foliage;

(c) exhibits a good basal branching character; and

(d) exhibits a compact growth habit.

Plants of the new cultivar differ from plants of the female parent plant primarily in leaf and flower color. The new cultivar of the present invention can be compared to ‘Fify Violet’ (U.S. Plant Pat. No. 11,577). However, in side-by-side comparisons, plants of the new cultivar are more vigorous and have flowers that are lighter and more pink in color than ‘Fify Violet’.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balpixropi’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Feb. 12, 2002. The readings were taken between 2:00 and 3:00 p.m. under natural daylights conditions.

Plants used for the following descriptions and measurements were grown in 10 cm pots for 12 weeks from rooted cuttings. The plants were produced from cuttings taken from stock plants and grown in a double poly carbonate covered greenhouse under conditions comparable to those used in commercial practice. A soilless growth medium was utilized while temperatures of approximately 68° to 75° F. (20° to 24° C.) during the day and approximately 55° to 65° F. (13° to 18° C.) during the night and light levels of 4,000 to 6,000 footcandles were maintained.

Fragrance.—None.

Lastingness of the bloom.—Approximately 4 to 7 days.

Aspect.—Flat.

Corolla.—Five petals with entire undulate margin, emarginated apex and attenuate base and smooth texture. Upper petal length is approximately 9 mm and width at widest point is 1.2 cm. Lower and lateral petals are fused at their bases. Lower and lateral petals overlap. Lateral petal length is approximately 1.4 cm and width at the widest point is approximately 1.1 cm. Lower petal length is approximately 1.3 cm and the width is approximately 9 mm. The color of the upper surface of the petals is closest to 73A with an area at the base of each petal of 71D forming an “eye”.
